Abstract

We report single yttrium sites anchored on carbon-coated TiO₂ for efficient and stable electrocatalytic N₂ fixation, delivering an NH₃ faradaic efficiency exceeding 11.0% and an NH₃ yield rate as high as 6.3 μg_NH₃ h⁻¹ mg_cat.⁻¹ at low overpotentials, thus surpassing many reported metal electrocatalysts.
